Background technique

There are many ways to open windows, which can be roughly divided into flat opening, push-pull, top hanging, bottom hanging, and inward opening and inversion. In building ventilation calculations, the reduction factor is often calculated. It is also the regular existence of this reduction factor that puts more constraints on architects in architectural design, often sacrificing part of the appearance effect to meet the rigid indicators of ventilation.

Therefore, the up and down lift windows have gradually appeared on the market, but the existing common lift windows have the following disadvantages: one is to use the transmission mode of the belt pulley to realize the lift, and if the lift window is larger and heavier, it will appear in this lift mode.
